Patent-ed Aug. 2, 1919. 1909. Serial No. 504,520.

To all whom it may cancer-a:

Be it known that I, CLINTON F. BLAKE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Dump Cars, of which thefollowing is a specification.

The invention relates to dump cars, and particularly to those of theside door type.

It has for its principal objects; the provision of a car of thecharacter specified having a container especially adapted to carrymaterial with which fluids are more or less mixed, such as garbage, andone having improved operating means for the doors; the provision of acar in which tight joints at the doors are insured, theprovision of acar of large capacity and one from out difficulty; and the provision ofa car having the frame-work of exceedingly simple and rigidconstruction.

I One embodiment of the invention is illustrated in the accompanyingdrawings, Where1n:

' Figure 1 is a partial side elevation of the car; Fig. 2 is an endelevation; Fig. 3 is a section on the line III-III of Fig. 1; Fig. ,4 isa partial plan view taken at one end of the car, and Fig. 5 is adiagrammatic view showing the arrangement of the operating The carcomprises the usual wheels 1, the frame thereabove and the box orcontainer mounted for tilting upon the frame. The support between thewheels and frame is not illustrated but is of the usual character. Theframe preferably consists of four chan-- nel beams 2, (Figs. 1 and 3)secured together by the cross or tie-beams 3. the heads of which projectslightly above the tops of the channel beams. The tops of these beamsserve as the rocking base forrockers 4. se cured to the bottom of thecontainer 5. These rockers are provided with flanges 6 so thatlongitudinal movement on the cross sheet metal and provided withtransverse stiffeners 7 which serve not only to stiflen the containerbut also to prevent too ready longitudinal movement of the contents ofthe car. Openings 8 are provided to pervmit any liquid which may bedirected into the car to flow from one compartment to another.

The car is tilted by means of a pair of pneumatic pylinders 9' and 10pivoted between gusset plates upon the cross beams as indicated inFig. 1. The pistons 11 and 12 are pivoted in lugs 13 on the rockers. Bythis arrangement the car may be readily rocked in both directions.Theconnections for supplying air are shown in Fig. 5, l t being thesupply reservoir, 15 and 16 being supply pipes leading to crossconnections 17 and 18 which simultaneously supply the op posite ends ofthe two cylinders, and 19 the valve by which the flow from the reservoiris controlled. The valve also controls the exhaust so that when fluid isbeing supplied to one of the connections 17 or 18, exhaust is occurringfrom the other connection. The opposite sides of the car are providedwith removable doors 20 and 21 which doors are automatically operated bythe tilting of the container, the arrangement of the links shown in Fig.2 accomplishing this result in the manner hereinafter described. Eachend of the car is provided with the sets of links as shown in Fig. 2,the two doors operating in precisely the same manner so that adescription of one set of links will SllifiCG for both. The door 20 ispreferably of the built up box construction indicated in Fig. 3, and isstiffened by the diagonal braces 22 (Fig. 1).

In'order to secure as tight a joint at the bottom as possible the dooris provided with hold the bottom of the door against outward movement.

The door is pivotally supported at its upper edge by the shafts 24located at each end thereof (Figs. 2 and 1). The shaft 24 is supportedby the links 25 and 26 pivoted respectively to the container at 27 andto' the pair of links 28 at 29. The pairs of links 28 are pivoted attheir inner ends to the member 30 secured to the frame. Thisarrangen'ient causes the right hand door 20 to be lifted bodily as thecar tilts to the position of the dotted lines in Fig. 2, and on theother hand permits the door.21 toremain in closed position during suchoperation, the left handpair of links 28 being free to rise. In order tocause the door to swing outwardly around its shaft 24 as it is raisedand thus give greater clearance, the link 31 is provided, which link ispivoted to the container at its inner end and carries a wire rope at itsouter end. This rope 32 is secured to a Wheel 33 such wheel being nonrotatable with respect to the door. As the door moves out the wheel willbe rotated counter clock-wise thus swinging the door to the positionindicated in the dotted lines. The Wheel is also provided with a stop 8awhich is adapted to engage the end of the link 31 when the door isclosed. This tends to still more securely maintain the door againstoutward movement. The upward movement of the door serves toautomatically disengage the stop from the end of the link. I

The bottom of the container is made inclined not only in order toprovide against leakage of a certain amount of fluid con tents but alsoto provide for greater an gularity of the container relatively to theframe and thus facilitate the discharge of its contents, and avoid thesticking action which occurs where material is pressed tightly against afiat surface. The greater inclination of the outer half of the bottomwhen the container is tilted secured by this inclined bottomconstruction is indicated in Fig. 2. The inclined bottom also providesincreased capacity in the container.

The provision of rockers instead of pivotal support for the container isadvantageous as the container is by this means carried bodily outwardand may be tilted to a greater degree than. would otherwise be possible,though certain features of my impIOVQCl construction are equally adaptable for use with pivotally supported containers and those wherein theoperating cylinders are.

located at the ends of the containers instead of below the frame.

Having .thus described my invention and illustrated its use, what Iclaimas new and desire to secure by Letters Patent is the following 2- 1. Incombination in a dump car, an elongated tilting container, and tranverse stiffening partitions spaced along the container, openings beingprovided at the bottom of the partitions.

2. In combination in a dump car, an elongated tilting container having adepressed bottom, dish shaped in cross section, and transversestiffening partitions spaced along the container and having their upperedges at substantially the height of the outer edges of the bottom.
